Minimally invasive distal pancreatectomy (MIDP) is nowadays an established standard procedure for non-locally advanced pancreatic lesions without celio-mesenteric vascular invasion. However, little is known about how the involvement of junior surgeons in MIDP affects postoperative outcomes. We performed a retrospective case series study in order to determine whether registrar involvement in MIDP is associated with adverse outcomes. Methods: Data were analyzed from a prospectively created database of consecutive patients undergoing MIDP. Only data from 91 patients who underwent MIDP for non-PDAC lesions were included. Patients were divided in 3 groups: Consultant P1 (first 20 MIDP, n=20), Consultant P2 (after 20 MIDP, n=44), and Registrar group (n=27). Conversion rates and 90-day postoperative outcomes were compared. Results: Conversion rates were 5%, 0%, and 14% in Consultant P1 and P2 and Registrar groups, respectively (P1 vs. P2, p = 0.312 and P1 vs. Registrar, p=0.376). Only Comprehensive Complication Index was higher in Registrar group compared to Consultant P1 group (13 vs. 3.7; p = 0.041). Comparison between Consultant P2 and Registrar groups resulted in a significant higher conversion rate (0 vs. 14%, p = 0.029), increased blood loss (77 vs. 263 ml, p = 0.018), and longer surgery duration (156 vs. 212 min, p=0.001) for registrars MIDP. However, no differences were found in clinically relevant postoperative pancreatic fistula (CR-POPF) (16 vs. 7.5%, p=0.282), Clavien-Dindo severe complication ≥3 score (11 vs. 4%, p=0.396), or length of hospital stay (9 vs. 9 days; p=0.614) between the consultant and registrar cohorts. Conclusions: With all the limitations of a retrospective study with a small sample size, junior surgeons' involvement in MIDP for non-PDAC lesions resulted in higher conversion rate, blood loss and duration of surgery without statistically significant difference on clinical outcomes compared to a consultant.
